The essential oil of Saccocalyx satureioides Coss. et Dur. grows in South-West of Algeria obtained by hydrodistillation and analysed by GC and GC/MS. The major components of oil are α-terpinéol (32.65%) and thymol (22.26%). The essential oil was subjected to the antifungal activities using seven fungi. The results of direct contact method showed that the oil was active against mycelial growth of fungal. All strains were inhibited at minimum inhibitory concentrations (MICs) as from1/880 v/v. Fusarium oxysporum f.sp. albedinis, Alternaria alternata MTCC 2724 and Cladosporium species MTCC 1003 were found to be more sensitive, being inhibited at MIC as weak as 1/1660 v/v. In the other hand, the tested essential oil against the majority of fungi showed total inhibition of the sporulation at concentration as from 1/370 v/v and partial spores’ germination with a very high rate.
